Speaking to student paper Cherwell, Annie Teriba, founder of Oxford’s Black Students’ Union, said: "Apparently, it’s okay to kick back in the Union bar relishing in a ‘Colonial Comeback’ cocktail. I am horrified that the Union thinks it’s okay to trivialise centuries of oppression and racist violence in the form of a refreshing drink.

"For some students, including myself, colonialism is a hard pill to swallow, especially as its legacy continues to visit violence upon black bodies. I shall be expecting an apology and explanation from the President for allowing the bar of an institution I paid money to join to be decorated with colonial pornography."

A statement on the Union's Facebook page said: "The Oxford Union apologises for this evening’s debate cocktail. This was an error of judgement, and will not be repeated."
